Analysis of the technological process of welding a membrane wall with Inconel 625 nickel alloy

The research carried out by the authors of this paper is focused on technological process Inconel 625 welding with MAG–CMT (Metal Active Gas-Cold Metal Transfer) method. was welded to substrate material, which 16Mo3 steel. Both materials are used produce so-called bimetallic tubes, in practice serve as a part equipment intended for waste incineration. For reason, tubes must withstand extreme conditions during their operation. Therefore, bimetal pipes highly stressed composite components that resist corrosion chemically aggressive environment. an extensive material and analysis production pipe bends supercritical bend 0.7D from cladding performed. In process, investigated possibilities CMT method without using oscillating movement head. most important factor deciding would be appropriate measure amount iron surface coating layer. authors’ builds previous area, mainly critical bending tubes.
